Memory of Water: Museum Under the Baths of Caracalla
A new museum has been created under the Baths of Caracalla in Rome. It accommodates a collection of valuable but forgotten archaeological finds. A network of four kilometres of formerly closed tunnels is located beneath the large ancient bathing complex. Thanks to the courage and determination of the State Office for Protection of Historical Monuments these are now open to the public. The underground atmosphere is very impressive, and the clear and simple design reflects the ethos of a society which attached great importance to the care of the body and the harmony of forms.
Architect: Fabio Fornasari, Bologna, Italy
Location: Baths of Caracalla, Rome, Italy
The new museum in the underground spaces of the Baths of Caracalla was inaugurated in December 2012. The exhibited material shown for the first time in the tunnels originally constructed to serve the baths primarily focusses on the architectural decoration that, apart from possessing ornamental quality, is more or less significant in terms of ideological content. Two gyms were the areas with most to offer in this sense.
The subterranean exhibition displays 45 marble artefacts expressly restored for this purpose, which have never been exhibited before. These include giant figurative capitals representing Hercules, Venus and Mars found in the frigidarium (cold room) and natatio (swimming pool), as well as fragments of a large bas-relief, which Caracalla had crafted to commemorate his martial activities, modelled on the Column of Marcus Aurelius and Trajan's Column. The bas-relief documented various campaigns against northern peoples in around 200 AD, and showed scenes of battles and military life.
The underground floors were originally fitted with overhead windows for air flow to prevent the stacked wood from rotting. Marina Piranomonte, the director of the antique baths, describes the construction as a maze of large, navigable tunnels (6 m high and 6 m wide) running under a large proportion of the site. There were also storage spaces for wood and furnaces to heat water for hot baths and saunas, as well as a water mill and a water regulation system: everything necessary for the comfort of the 6,000 to 8,000 people who visited the complex every day. The marble items were brought back from various different places in 1996. They were stored underground for fear of theft and 16 years passed before these valuable artefacts could be presented to the public again.
The exhibition is located in two parallel tunnels. Starting from the entrance stairs, visitors are first conducted to two exhibition islands concerned with the gyms and the frigidarium, and then on to the second tunnel with islands dedicated to the natatio and the libraries.
The architect Fabio Fornasari, responsible for the concept and curacy of the exhibition, provided an insight into his involvement in the project. When he first descended below ground, he suddenly found himself in a suggestive environment, full of opportunities – although at first glance like any old subterranean tunnel, without any indication of the complexity and intelligence of a gallery that allowed slaves to store, transport and burn wood essential for the functioning of the baths. The wet floor, water and soil washed out of the walls gave rise to the idea to restore the former magnificence of the baths: the only missing element was the water itself. At this point, he decided to explore the Eternal City's most evocative water – the water of the Fontana di Trevi. In the course of this, he discovered the specific colour effect with which the precious water should flow, a colour that could even appear soiled, but with a depth that would reflect the columns and reinforce their strength: this colour was "glauco" (blue green).
To create the desired effect, the coloured parts were treated with a little dirt and a thin layer of resin with "glossy" chromatics, to give the symbolic water surface the appearance of movement.
Platforms lit from below and covered with the new foil, are partly used to illuminate the false columns with huge capitals of approx. 1.5 m resting on top. Originally located at heights of 20 m, the maximum height of the capitals is limited to 8 m in the galleries. With the help of ingenious lighting, the elements are however displayed in a dimensionally appropriate manner from a visitor perspective.
The exhibition shelves, showing fragments of the frieze from the gyms, call to mind a natural biological cataloguing system, rather than a mere carrier construction. For storage of the artefacts, the architect designed a "wireframe" of time cells made of steel, representing the chapters of a story. Each cell places the work of art in a precise position within the whole structure (originally nearly 100 m long) and specifies the exact time in the historical narrative in this way (at a scale of 1:1). This emphasises the educational dimension of the exhibition. Illuminated from below, the frame furthermore projects its own shadow on the barrel vault, accentuating geometry and depth, and honouring the complexity of the work accomplished by the Roman engineers.
The construction of the arrangement is the fruit of 20 years of work by Gunhild Jenewein of the Austrian Historical Institute in Rome. And the visitor, attracted by the fascination surrounding underground places, comes to see the stars again and brings along one more piece of memory: that of water.
